    摘要: A system and method for carrier deferral for full duplex energy efficient Ethernet (EEE) physical layer devices (PHYs). A carrier deferral signal can be asserted to a media access control layer to indicate to the media access control (MAC) layer that transmission of data is to be deferred due to a power savings initiative in the physical layer device. In one example, the carrier deferral signal is used when a PHY is awakened by the MAC when the MAC has something to transmit. In another example, the carrier deferral signal is used when a PHY is switching link rates.

    摘要: An Ethernet network may comprise multi-rate link partners that may be coupled via an Ethernet link. The Ethernet link may comprise a plurality of channels wherein one or more may be silent and/or idle channels set to a low(er) power that may enable energy efficiency. Silent channels may be utilized for transmitting signals comprising one or more distinct physical patterns for controlling data rate transitions. For example, symbols may be utilized for generating the distinct physical patterns. The distinct physical patterns may communicate a new data rate, when to transition the data rate, which channel(s) may bear the data rate transition and/or a method for implementing the data rate transition. The method may comprise activating or suspending a data traffic channel, modifying a signal constellation, modifying PAM levels and/or adjusting inter-frame gap. The new data rate may be determined based on past traffic and/or expected traffic on the network link.

    摘要: In an Ethernet network comprising link partners that are coupled via an Ethernet link, an energy efficient network (EEN) communication control policy may be established above a MAC layer. The EEN control policy may determine a power level mode of operation for the link partners. Power level mode control data may be communicated from hardware, software and/or firmware of upper layer protocols to PHY devices. The control data may specify when, where and/or how long to implement the power level mode. The control data may be communicated via a “magic” packet comprising start and/or end of frame delimiters and bits that indicate the power level mode. The PHY devices may detect, parse and/or interpret the “magic” packet and may enter and/or exit a lower power mode of operation. The PHY devices may respond to by generating a magic packet and sending the packet to upper layers.

A time stamp value may be generated for the encapsulating PDU. The encapsulating PDU may include at least one data type identifier, which indicates that the encapsulating PDU contains the generated response data.
